High-efficiency low-noise low-fault freezing crystallization pot stirring speed reducer

Abstract

The utility model discloses a high-efficiency, low-noise and low-fault stirring speed reducer for a freezing crystallization pot, which is used in a freezing crystallization process of ferrous sulfate for producing titanium dioxide by a sulfuric acid method. Comprising a triangular rubber belt flexible transmission speed reduction module, a bevel gear transmission speed reduction module and a planetary gear speed reduction module, and three transmission modes of triangular rubber belt transmission, bevel gear transmission and planetary gear transmission are combined to form the vertical stirring speed reduction device. After the driving motor is decelerated through transmission of a triangular rubber belt, speed reduction and torque increase are further achieved through transmission of a bevel gear and a planetary gear. The device has the advantages that the fault-free operation period reaches 48 months and is two times that of an existing device; the transmission efficiency is about 84% and is higher than that of a triangular rubber belt and worm wheel and worm transmission combined device. The device has excellent performance in the aspects of heat dissipation, noise control, failure rate reduction and transmission efficiency improvement, better meets the working requirements of the freezing crystallization pot, provides reliable power support for the production process, and ensures high-efficiency, stable and low-noise operation of production.
